This is a must win game, for a multitude of reasons a) We can't loose ground on those above us, b) we need to remove the blip that was Oldham and move forward.
I don't agree with you about Podolski and Giroud - they may of started slowly, but they are now showing a bit of form.. The main issue we will face is the pace of their attack, especially Walcott who has hit a great patch of form - which is lucky for Arsenal as Carzola has gone off the boil a bit.
The key to this is the midfield, Diaby is another player like Diame - strong, atheltic and a physical presence.. Containing him and Wilshere will be paramount to building a platform for victory. I'd like us to be a bit more physical in the opening few minutes (within the letter of the law obviously!) Go clattering into a tackle and show we are here and wont be lying down - Oldham did it on Allen twice and it worked, we need to set a tone early.. Nothing wrong with a bit of hard tackle to start with - remember Carragher doing it to Nani? Worked a treat.
I think the team selection should be straight forward, but I'm sure against better judgement we shall be seeing Carragher over Skrtel - something I am massively against, this isn't a dig at Carragher as he clearly has a role to play in our current set up. I worry that Carragher simply wont be able to handle the likes of Walcott and Podolski and their pace, and if they bring on Ox Chamberlain, Carragher will drop very deep - when this happens we will start to see huge holes in front of the back four and expect the likes of Carzola and Wilshere to exploit this. We need to push forward as a unit and keep our shape or they will catch us on the counter at blistering speed and really punish us.
So Johnson and Enrique on the flanks is essential, but they need to watch being caught up field leaving us exposed on the counter.
I'd go
Reina
Johnson Skrtel Agger Enrique
Gerrard Lucas Henderson
Suarez Sturridge Borini
This midfield 3 has the perfect balance - Lucas (Destroy/pivot) Gerrard (pulling the strings, bursting forward) Henderson (Energy, high pressing, link play)
The attacking 3 also all have pace and will press. I'd expect Lucas to be tasked with man marking Carzola (A lovely strong tackle early should hopefully make him a bit more nervous)
If we press them hard from the off and disrupt their game we should win. On paper I'd say we are very evenly matched, but we have Suarez..
